v is the initial speed of mass A. I think v - 0 = [v][/B] - [v][/A] is correct since the the collision is elastic. And subbing v = [v][/B] - [v][/A] into [m][/A]v = [m][/B][v][/B] + [m][/A][v][/A], I was able to get the answer. Thanks for the advices.

Homework Statement Small object A (mass: [m][/A]) is traveling in a linear path on a horizontal surface and collides elastically with small object B ([m][/B]), at rest on the same line, with a speed of v. Friction between the objects and the horizontal surface is negligible. What is the...
